useful Improvements in Gas-Generators for Explosive-Engines, of whichthe following is a specification. v

My invention relates to that class of gasgenerators or carbureters forexplosive engines, in which a heavy hydrocarbon, generally crude oil, issubjected, in its course through the generator, to a heating medium,usually the exhaust gases from the engine to which it supplies theexplosive mixture.

The object of my invention is to control the flow of heating medium insuch manner that it may readily, and by simple means, be deflected inwhole or in part, as may be required, from its course through thegenerator; and to this" end my invention consists in the novelconstruction and arrangement of a controlling valve, in connection withthe inlet and exit of the channel by which the heating medium isconducted through the generator; as I shall now fully describe, byreference to the accompanying drawings in which:

Figure 1 is a vertical section of my improved generator, the controllingvalve being in position to allow the heating medium to pass in fullvolume into and through the generator. Fig. 2 is a vertical section ofpart of the generator showin the controlling valve turned to divert allthe eating medium from the generator and not let it enter therein. Fig.3 is a horizontal section on line 00-00 of Fig. 1.

The body of the generator here shown, is of. a well 'known type, and Iuse it for the purpose of illustrating any generator in which the oilflows from above downwardly through a tortuous channel to a residueoutlet; and in its course is subjectedto the heat of the exhaust-gaseswhich are admitted below and thence flow upwardly through a channelcontiguous to the-oil channel, and

are dischar ed above, afteran interchange of 'heat. In tisgenerator'the'shelll is formed internally with a'vertical series ofoil chamhers 2, the floor of each of which is provided with flanges 3,which extend alternately from opposite sides, as seen in Fig. 3, saidflanges form-in an extensive and tortuous channel 'throug which the oilflows; The endof the floor channel of one chamber communicates with thebeginning of the floor channel of the next, by means of passages 4. Atthe beginning of the first floor channel is the oil inlet 5, and at theend of the last floor assage is the residue outlet 6. Thus the o' entersat 5,

flows through the channels between the flan es 3 and from one chamber tothe next, unt' the residue is drawn off at 6. Between each oil chamberis formed the sections 7 of the channel for the heating medium, saidsections communicating at their ends by means of sections 8, so that onecontinuous heating channel is formed, having an inlet below at 9 and anoutlet above at 10.

This is a sufficient description to illustrate atype of generator towhich my improvement is applicable. The shell 1 has as art of itsstructure removable outer walls, t rec of which are designated by 11, asshown clearly in Fig. 3. The fourth marked 12 embodies my im rovement.It is hollow and is formed wit a partition 13, extending from below, andterminating short of its top. This partition divides the cavity of thewall into an inner passage 14, and an outer passage 15, whichcommunicate over the top of 16 are ribs in these passages.

the partition. The lower end ofthe inner passage 14, communicates withthe inlet 9 of the heating channel of the generator. With the outerpassage 15, at any point in its length, the inthe position shown in Fig.1, the exhaust gases will pass it from the outer passage 15, and flowdown the inner passage 14, and enter the generator at 9. Thence theyflow through the generator and out at 10, and thence the out et pipe 19.

When the valve is turned to the position shown in Fig. 2, the exhaustgases pass ast the upperpart of the valve 20 to controlling the flow ofthe heating medium for all conditions, and materially simplifies thistype of generator. A further advantage to be noted lies in the hollowwall 12, with its double passage; its outer passage 15 through which thegases may be directly diverted, being far enough removed from thegenerator roper, to materially reduce its heat when or any pur ose ithas to be worked with.

Having t us described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a gasenerator for explosive engines, ashell forme with suitable interior channels for the oil and for theheating medium;

- an entrance connection for the heating medium communicating with theinlet to the heating medium channel in the shell; an outlet connectioncommunicating with the exit from said heating medium channel, and alsocommunicatin with the entrance connection; and a va ve seated'in thecommunications of the outlet connection constructed and arranged withrelation to said connections whereby the valve is adapted to close oropen one while opening or closing the other or to partially open both.

2. In a gas-generator for explosive engines, a shell formed withsuitable interior channels for the oil and for the heating medium, thechannel for the heating medium having an inlet below, and an exit above;a wall on one side of said shell, formed interiorly with an outer and aninner passage communicating above, the lower end of the inner passagecommunicating with the inlet of the channel in the shell for the heatingmedium; an inlet pipe for said heating me ium communicating with theouter wall-passage; an outlet pipe for the heating medium communicatingwith said outer wall-passage and, also communicating with the exit ofthe channel in the shell for the heating medium; and a valve seatedin'said wall, disposed and fashioned to open or close the communicationbetween the outer and inner passages and the communication between theexit of the heating medium channel in the shell and the outlet pipe,while closing or opening the communication between the outer wallpassageand the outlet pipe, or to partially open or close all of saidcommunication.

3. In a gas-generator for explosive engines, a shell formedwith'suitable interior channels for the oil and for the heating medium,the channel for the heating medium having an inlet below and an exitabove; a hollow wall forming one side of the shell, said wall havingwithin it a vertical partition dividing it into an outer and an innerpassage which communicate over the top of the partition, the lower endof the inner passage communicating with the inlet of the channel in theshell for the heating medium; an inlet pipe for said heating mediumcommunicating with the outer wall-passage; an outlet pipe for theheating medium communicating with the upper end of said outerwall-passage, and also communicating with the exit of the channel in theshell for the heating medium; and a valve seated in said wall disposedand fashioned to open or close the communication between the outer andinner passages and the communication between the exit of the heatingmedium channel in the shell and the outlet pipe, while closing oropening the communication between the outer wall-passage and the outletpipe, or to partially open or close all of said communication.

4. In a gas-generator for explosive engines,

communicating with the inlet of the channel in the shell for the heatingmedium, an inlet pipe for said heating medium communicating with theouter passage, an outlet pipefor the heating medium communicating withsaid outer passage and also communicating with the exit of the channelin the shell for the heating medium and a valve to open or close thecommunication between the outer and inner passages and the communicationbetween the exit of the heating. medium f channel in the shell and theoutlet pipe, while closing or opening the communication between theouter passage and the outlet pipe, or to partially open or close all ofsaid communication, said inner passage being directly interposed betweenthe shell and the outer passage to entirely s ace ,the same and servingto protect the she from the heatof Y the products when passing directlythrough the outer passage.

5. In a gas-generator for explosive engines,-

a shell formedwith suitable interior .channels for the oil and for theheating medium; an entrance connection for the heating mediumcommunicating with the inlet to the heating medium channel in the shell,an outlet connection communicating with the exit from said heatingmedium channel and also communicating with the entrance connection and avalve arranged in the outlet connection directly adjacent the exit fromthe name to this specification in the presence of heating medium channeland constructed two subscribing witnesses.

and arranged with re aticn to said connec 1 tions whereby the valve'isadapted to close GOMER C 5 or 'open one While opening or closing the IWitnesses:
